The Endocrine System Hormones are chemical substances that are secreted by organs or by cells of organs in one part of the body and are carried by the bloodstream to other organs or tissues, where they control or regulate the development or function of those structures.

- Testosterone (androgen) is a hormone. Hormones are powerful chemicals that help keep our bodies working normally. The term hormone is derived from the Greek word, hormo, which means to set in motion.And that’s precisely what hormones do. They stimulate, regulate, and control the function of various tissues and organs.Made by specialized groups of cells within structures called glands, hormones are involved in almost every biological process, including sexual reproduction, growth, metabolism, and immune function.njected into a growth-stunted child, the child grew taller. At that time, growth hormone was extracted from the pituitaries of cadavers. As heat destroyed this pituitary extract, it could not be pasteurized and the problem of transmitting disease also existed. In 1986 the Eli Lilly and Company developed Humatrope.

Hormone hormone. a chemical transmitter substance produced by cells of the body and transported by the bloodstream to the cells and organs on which it has a specific regulatory effect. adj., adj hormo´nal. Hormones act as chemical messengers to body organs, stimulating certain life processes and retarding others. chemical transmitter substance produced by cells of the body and transported by the bloodstream and other means to the cells and organs which carry specific receptors for the hormone and on which it has a specific regulatory effect.

Hormone A hormone (from Greek ὁρμή, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.ormones affect distant cells by binding to specific receptor proteins in the target cell resulting in a change in cell function. When a hormone binds to the receptor, it results in the activation of a signal transduction pathway.

Hormone hormone. 1  organic substance secreted by plants and animals that functions in the regulation of physiological activities and in maintaining homeostasis. Hormones carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them.

Medical Definition of Hormone Medical Definition of Hormone. Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. Many hormones are secreted by special glands, such as thyroid hormone produced by the thyroid gland. Hormones are essential for every activity of life, including the processes of digestion, metabolism, growth, reproduction, and mood control.

Estrogen and Testosterone Hormones The definition of a hormone is a chemical substance produced by an endocrine gland that has a specific effect on the activities of other organs in the body. The major female and male hormones can be classified as estrogens or androgens.Both classes of male and female hormones are present in both males and females alike, but in vastly different amounts.Most men produce 6-8 mg of the male hormone testosterone (an androgen) per day, compared to most women who produce 0.5 mg daily.Female hormones, estrogens, are also present in both sexes, but in larger amounts for women.oth classes of male and female hormones are present in both males and females alike, but in vastly different amounts.

Print Options Hormones. Chemistry of Hormones. Hormones are long-distance chemical signals that are secreted by the cells to the extracellular fluid and regulate the metabolic functions of other cells. Most hormones are amino acid based, but gonadal and adrenocortical hormones are steroids, derived from cholesterol.
